THREAD-GUlDlNG AND TENSION-REGULATING DEVlCE FOR SPOOLING AND WINDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 369,868, datedSeptember 13, 1887.

A Application filed January 25, 1886. Serial No. 1%).715. (No model.)

To aZZ whom it may concern:

Be it known that I, ARTHUR W. MATHEW s0N,of the city of Fall River, county of Bristol,; and State of Massachusetts, have invented certain new and useful Improvements in Thread- Guiding and Tension-Regulating Devices for Spooling and Winding Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying draw ings, forming part of this specification.

My invention relates to the class of spooling and winding machines which wind the cotton thread onto rotating spools from bobbins or cops mounted upon spindles.

In the ordinary spooling and winding machines the great distance between the delivery end of the bobbin and the eye of its threadguide allows the thread to widely balloon out and form itself into loops. This looping and beating about causes'such a great air-drag as to seriously injure the uniformity of the filaimprovements in this class of machineswhere by in spooling and winding thread high speed can be obtained without the usual result-ant injury to the thread,which is delivered to the I spool rapidly and in a very perfect condition by my device.

To the above purposes my invention consists in the very close relative adjustment of the delivery end of the bobbin and of the cooperating thread guide, and in other sub-combinations, all hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents afront elevation of my improvements with the bobbin mounted upon its spindle. Fig. 2 represents a side elevation of Fig.

1, the broken lines representing the clamp, with its thread-guide and friction roll tilted back into abnormal position. Fig. 3 represents a side elevation of another form of my device, part shown in section. Fig. 4 represents a top plan view of my devices with the frictionroll removed. Fig. 5 represents a sectional view on line 5 5, Fig. 2, the friction-roll being removed and the standard. broken off.

. In the said drawings like numbers designate like parts throughout.

In the illustrations I have shown only the immediate parts of the machine which have to do with my device, so the spool and its adjuncts are not shown. The spindle-step 6 is located upon the base of the supporting-standard 7 and carries the dead-spindle upon which the ordinary bobbin, 8, is mounted. The standard 7 is a tapering upright piece having four lateral ribs, though it may be of any shape, and at its head broadens out and carries two cars, 9, which are perforated to receive the pivot-bar 10, upon which sets and turns the lower plate, 11, of the thread-guide clamp. This plate 11 is quite thick and is suitably formed to have tilting play upon its pivot equal to the difference between its normal and abnormal positions.- (Shown in Fig. 2 in full and broken lines, respectively.)

-Upon the upper face of plate 11 is movably secured the guide clamp or plate 12 by means of screw 13, which passes through the guide clamp or plate '12 into plate 11. The plate 12 has upon its lower face two semi-cylindrical longitudinal grooves, 14, running parallel. Upon one side the plate 12 has an L-shap'ed arm, 15, the main and upright part of which is broad and fiat, with a notch, 16, at its upper end. This arm 15 is placed with its flat face somewhat diagonal to the sides of the plate 12,

which bears it, which is well shown in Fig. 4, and which is designed for a purpose hereinafter described. The plate 12 can be easily turned about its pin 13 on the face of plate 11.

The friction-roll 17 is drum-shaped, and is covered with clothing 18, made of flannel or other similar suitable material. At the center of one end of roll 17 is fixed the screw-pin 19, which rests in notch 16 of arm 15, and is adapted to allow the roll 17 to rotate on its axis for new adjustment.

The thread-guide 20 consists of a doubled wire having the closed end formed into an approximate W form, the upper apex: of which is constructed with a loop-like guide-eye, 21, curved bey'ond's'aid apex and h'a'ving the ends or shouldersofthe loop arranged one above the other, with a slight opening therebetween looking toward the bottom of the W form, said opening beingintended for the admission of the thread into eye 21 when the thread is fed in between the outer apexes and toward the inner apex. of guide-eye 21,with the diverging wires leading to the opening of the eye, admits of the thread 23 being fed therein by the thread be; ing carried s'idewisein toward the opening of the eye into the position shown in -the figures.

The guide-eye is thus self-feeding, since it is not required to thread the yarn or thread lengthwisethroughsaid eye; but it may be easily forced therein by a slight pressure sidewis e. From the freeends of the W form extend rearwardly the-parallel wires or strands, as shown. One'of these parallel wires (shown in the drawings as the left-hand one) extends rearwardly a little longer than the other, which remains straight, andthis longer wire is bent at right angleson itself and formed into the guide-eye 22. This threadrguide 20 is. placed upon theupper face of the lower plate, 11, and clamped thereon by the upper plate, 12, so that the parallelwires take into grooves 14 upon plate 12, and can" be reciproeated longitudinally therein. Bymeans of screw 13 the guidecan be clamped fast when adjusted, as desired. Obviously, byloosening the screw 13, by which the guideclamp or. plate 12 is swiveled to the tilting plate 11, said guideclamp 12 may be readily swung on the swivel in a plane cutting the axial lined the bobbin spindle or support 30 or 40, and-the clamped thread-guide carried by said clamp may thereby have its guide-eye 21 adjusted laterally over the nose of the bobbin or cop 8 anywhere iuan arc of which the'swivel-screw 1 3 is the center. The thread 23, wound upon bobbin 8, runs from thence through guide-eye 21 over the friction-r0111? down throughiguide-eye 22 onto the spool. 1(Not'shown.)

The friction roll 17 is, by means of the construction of its supporting-arm 15, adjusted to-haveits longitudinal axis placed otherwise than normal to a line at right angles to the axial line of the bobbin-spindle or inclined to the vertical plane containing the standard 7 and the axial line of the bobbin-spindle-or support," and thereby allowingthe track of the thread 23 over the roll 17 to bediagonal to said axis, so that: by slightly rotating the roll upon its pin 19 the thread will find anentirely different track. This adjustment of the roll causes the' clothing of the same to last much longer than ordinarily and saves time in the frequent replacement of the worn clothingwhich is usually required. I

By my construction of theclamp ll 12, the thread=guide isadjustable therein longitudinally by virtue of the wires sliding in the grooves 14 and laterally in an arc Whose center is the screw 13 by virtue of the said screw.

Obviously this construction sition.

The longitudinal adjustment of the threadguide is the'adjustment of the thread-guide "and in the said plane. This thread-guide20,

because of these adjustments, can be readily and accurately adjusted to have its guide-eye 21 brought directly over the end of the bobbin and centered Very close down upon-the same, thereby preventing any damage to the thread by its beating and chafing about the head of the bobbin. These adjustments of my device reduce the ballooning to the minimum.

The clamp 11 12, rotating on its pivot 10 and carrying the thread-guide 20 and friction roll 17, can be tilted back into the position shown by the broken lines in Fig. 2. When in this back position, the bobbin 8 can be readily withdrawn from its spindle and replaced by another when the clampis-tilted is made part of the standard 7 and is stationary. The tilting motion is now given to the spindle or skewer30, which is hinged by its head 31, turningon pivot 32, fixed across the recess 33, made in the step 6. From recess 33 runs-the cavity 34, extending back into-the base of standard 7, where the flat spring 35 is secured in position by the screws 36. The free end of spring 35 projects across recess 33, and here the end of the head'31 of the spindle rests upon it to maintain the spindle in operative po- Upon the head 31 is a flat face running forwardly and upwardly, against which the spring 35 presses, when the spindle is drawn forward at the top, to allow the bobbin 8 to clear the threadguide 20, which is here stationary, in the insertion and withdrawal of the bobbing This motion of the tilting spindle and'bobbinis an easy spring-acted motion, and any of the various constructions ordinarily employed upon the skewersof loomshuttles may beadopted for use in this part of my device.

In Fig. 4 I'have shown the spindle 40as very short, to better enable the mounting and withdrawal of the bobbin. However, any well-known suitable means may be here used to maintain the bobbin in operative position.

It is obvious that by my constructions either of the tilting clamp and'adjuncts, with spindle stationary, or by the tilting spindle and bobis objectionable-as damaging to the structure ofthe thread. i

Practical use of my device shows that it admits of such high speed that the thread makes double the number of circuits about the bobbin that the ordinary machines admit of, and that high speed does not lacerate or break the thread.

Obviously my device may be used with all its advantages in spinningall kinds of yarns. The yarn is composed of filaments arranged in regular systematic order, and if this order is preserved tillthe yarn is woven into fabrics these fabrics will be all the more perfect. My device preserves this desired smoothness of structure of the thread and yet permits of running at a high speed.

There may be various modifications made in all parts of my device without departing from the spirit of my invention as herein described and claimed.

I am aware of the heretofore construction of means for adjusting a thread-guide in an are lying in a vertical plane parallel to the axial line of the bobbin-spindle and also in a line normal to the said plane, and henceI disclaim such construction. I am not aware of the heretofore employment of means for the adjustment of a thread-guide longitudinally in a line and laterally in an arc across the bobbin-nose; and,-therefore,
